NMR probe coils designed to operate at two different frequencies, producing a strong and homogenous magnetic field at both the frequencies. This single coil, placed close to the sample, provides a method to optimize the NMR detection sensitivity of two different channels. In addition, the present invention describes a coil that generates a magnetic field that is parallel to the substrate of the coil as opposed to perpendicular as seen in the prior art. The present invention isolates coils from each other even when placed in close proximity to each other. A method to reduce the presence of electric field within the sample region is also considered. Further, the invention describes a method to adjust the radio-frequency tuning and coupling of the NMR probe coils.

A pheromonal compound produced byhas been identified as 5R-(3'-O-[&#x3b2;-D-glucosyl]-tetrahydro-3&#x2032;R,5&#x2032;R-dihydroxy-6&#x2032;S-methyl-2H-pyran-2&#x2032;R-yloxy)-2-hexanone. The novel compound, in combination with other ascarosides, elicit a synergistic signaling response from various adult malespp.
